3 * Bacula Director -- verify.c -- responsible for running file verification
5 * Kern Sibbald, October MM
7 * This routine is run as a separate thread. There may be more
8 * work to be done to make it totally reentrant!!!!
10 * Current implementation is Catalog verification only (i.e. no
11 * verification versus tape).
13 * Basic tasks done here:
15 * Open connection with File daemon and pass him commands
17 * When the File daemon sends the attributes, compare them to
